Abstract
The utility model discloses an extrusion die, which comprises an external die sleeve, an internal die sleeve and an inner core arranged on the inner die sleeve. The extrusion die is characterized in that the external die sleeve and the internal die sleeve are integrally molded and have the same thickness of 45-50mm; and a desquamating conical angle with 9-11 degrees is formed at the end part of internal die sleeve, so that the service life is effectively prolonged, the maintenance is more convenient and the cost is reduced.
Description
Technical field
The utility model relates to a kind of extrusion die.
Background technology
In existing large-size extruder, special indirect extrusion machine, extrusion die are to guarantee to produce one of successional critical component.See Fig. 2, extrusion die on present most of indirect extrusion machine is a split pattern, in the hot extrude process, bolt and mould easy deformation, and between outer die casing and the interior die sleeve slit may appear in the split pattern, sometimes metal can dig into from the slit, thereby cause the outer die casing of split pattern to break, reduced the service life of mould, the I﹠M of split pattern is also inconvenient, the installation of part need be very accurate in the split pattern installation process, in order to prevent the above-mentioned consequence that the slit occurs and cause, therefore need further make improvements.
The utility model content
Technical problem to be solved in the utility model is the present situation at prior art, and a kind of long service life, extrusion die easy to maintenance, lower-cost are provided.
The utility model solves the problems of the technologies described above and the technical scheme that adopts is: a kind of extrusion die, comprise outer die casing, interior die sleeve and the inner core that places internal mold to put, and it is characterized in that: described outer die casing and interior die sleeve adopt integrated siamese part.
As improvement, described interior die sleeve is identical with the thickness of outer die casing, and the thickness of interior die sleeve and outer die casing is 45mm～50mm.
As improvement, the end of described interior die sleeve is provided with the decortication cone angle, and this decortication cone angle is 9 °～11 °.
Compared with prior art, advantage of the present utility model is: adopt outer die casing and interior die sleeve one-body molded, make it save the connectors such as screw that outer die casing is connected with the internal mold cover, reduced cost, and safeguard also convenient, the one-body molded slit that may occur between outer die casing and the interior die sleeve of also effectively having prevented, metal can not crept in the slit and cause the split pattern outer die casing to break, effectively raise the service life of mould, interior die sleeve is identical with outer die casing thickness, make the front end can be too not heavy and the phenomenon that leans forward, thereby guaranteed interior die sleeve center non-migration, made its recipient inwall of can not damaging, put at internal mold the decortication cone angle is set, the metal scurf that remains in the recipient is easily come off, also can prolong the service life of mould.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model;
Fig. 2 is the structure cutaway view of conventional extruded mould.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of as described in Figure 1 extrusion die, comprise outer die casing 1 and interior die sleeve 2, there is an inner core 3 to be installed on the interior die sleeve 2, this inner core 3 utilizes pin nail 4 to be connected with outer die casing 1, described outer die casing 1 adopts integrated siamese part with interior die sleeve 2, the stability and the antitypy of entire die have been improved effectively, and saved that outer die casing 1 is connected required connector 5 (as shown in Figure 2) with interior die sleeve 2 in the split pattern of conventional extruded mould, reduced cost effectively, adopt the one-body molded generation that can also prevent slit between outer die casing 1 and the interior die sleeve 2, make metal can not pierce the slit and cause outer die casing 1 to break, die sleeve 2 is identical with the thickness of outer die casing 1 in described, and interior die sleeve 2 is 45mm～50mm with the thickness of outer die casing 1, make the mould front end can be not overweight, and the phenomenon that leans forward, thereby guaranteed that interior die sleeve 2 centers are not offset, the recipient inwall prevents to damage, also be provided with decortication cone angle 6 in the end of interior die sleeve 2, this decortication cone angle 6 is 9 °～11 °, the metal scurf that remains in the recipient is come off easily, guaranteed that the metal scurf does not encase mould, has prolonged the service life of entire die effectively.
Claims (3)
1. extrusion die, it comprises outer die casing, interior die sleeve and the inner core that places internal mold to put, and it is characterized in that: described outer die casing and interior die sleeve adopt integrated siamese part.
